Collaborative Research: Upward and Outward: Tibetan Plateau Growth and Climatic Consequences

[0507708]本项目的目的是研究青藏高原东北段地形、变形、大气环流和气候之间可能存在的反馈关系。该提案旨在了解高原隆升的时间和空间格局，并由此推断隆升的机制（密度沉降和/或渠道流动），并确定隆升在局部、区域和全球尺度上对气候变化的影响（如果有的话）。为此，pi将采用多种方法和人员：Molnar：项目协调员，分析GPS，重力和地震数据，建模变形和大气相互作用；伯班克：磁地层学，sed。构造、锆石U-Pb定年、构造和平衡截面；Clark：结构和平衡截面，U-Th/He测年，重力和地震折射数据分析；Garzione：盆地沉积物的U-Pb碎屑锆石、氧碳同位素、结构和平衡截面；Kirby：结构和平衡截面，U-Th/He测年子集；法利：男女约会；Roe：大气模拟（利用氧气数据）；中国合作者：磁地层学，磷灰石裂变径迹，提供GPS和地震数据。

0507708RoeThe goal of this project is to study the possible feedback between topography, deformation, atmospheric circulation and climate in the NE portion of the Tibetan plateau. The proposal seeks to understand the timing and spatial pattern of plateau uplift and from this, infer the mechanism of uplift (density foundering and/or channel flow) and determine what effect, if any, the uplift had on climate change at local, regional and global scales. To do this, the PIs will employ a variety of methods and personnel: Molnar: project coordinator, analysis of GPS, gravity and seismic data, modeling of deformation and atmospheric interactions; Burbank: magnetostratigraphy, sed. structures, U-Pb dating of zircons, structures and balanced cross sections ;Clark: structures and balanced cross sections, U-Th/He dating, analysis of gravity and seismic refraction data ;Garzione: U-Pb detrital zircons, oxygen and carbon isotopes of basin sediments, structures and balanced cross sections; Kirby: structures and balanced cross sections, subset of U-Th/He dating;Farley: U-Th/He dating; Roe: atmospheric modeling (utilizing oxygen data); Chinese collaborators: magnetostratigraphy, apatite fission track, provision of GPS and seismic data.
